Abstract

Abstract 1-Sulfonyl-1,2,3-triazoles undergo a Doyle–Kirmse reaction upon treatment with allylic sulfides in the presence of a rhodium(II) catalyst to afford α-allyl-α-sulfanylimines. Terminal alkynes are regioselectively multifunctionalized by the introduction of C–N, C–S, and C–C bonds through a one-pot sequence consisting of a [3 + 2] dipolar cycloaddition reaction with azide and subsequent Doyle–Kirmse reaction.
